The 'age' of your blood could predict dementia risk, new study suggests

A new study by the Alzheimer’s Association suggests that a person’s biological age, measured through blood metabolites, can predict dementia risk. Researchers found that a higher 'MileAge delta' (difference between metabolite-predicted age and actual age) correlates with increased risk of all-cause dementia, particularly vascular dementia. Those with both a high MileAge delta and the APOE gene had a 10-times greater dementia risk.
